She's smart and sexy, which is exactly why producers of the Buick Enclave commercial hired Victoria's Secret stunner Marisa Miller to star in the ad!

Dressed in a bikini and cover-up, the model, who has appeared in countless swimsuit spreads for VS, Maxim and Sports Illustrated, makes surfers and bikers collide at the beach as she packs her surfboards into her Buick in the sizzling commercial.

But none of that should come as a surprise! Marisa herself admits that after years of marriage, her husband still finds her irresistible — just like the rest of the world!

"Not too long ago, my husband walked into a wall," Marisa admits in the behind-the-scenes footage, "and that made me feel good after five years of marriage, you know? I could still make him walk into a wall!"

And of course, the Buick Enclave plays a supporting role in the commercial, which debuts on TV Monday, May 14.

"Mt first impression of the Buick was how sleek and sophisticated it looked and knowing all the features it has. It was cool to see a car that looks that great and isn't enormous either to have all that space in the back," Marisa gushed, adding, "I was really impressed."
